  • Issue with Engineer’s thumb Compressor

    Hi,
    I’m struggling with this project, I have checked the connections, but I cannot figure it out myself.

    the effect works when the ratio pot is between minimum and increasing to about 15%...after that I hear a very low and distorted signal in the background

    I have checked the voltages at the IC’s hoping that will help you in assisting me.
    Thanks!

    IC1:(LM13700)
    1) 1,86V
    2) 1,32V
    3-4-5)3,8V
    6)-0,1V
    7)97mV
    8)5,02V
    9)5,18V
    10)94mV
    11)7,62V
    12-13)1,93V
    14)1,74V
    15)2,04V
    16)-0,1mV

    IC2(TL074)
    1-2)3,81V
    3)3,66V
    4)7,62V
    5)3,48V
    6-7)3,8V
    8)2,62V
    9)1,87V
    10)3,65V
    11)0.1mV
    12)3,48V
    13-14)3,81V

  • Engineer’s thumb not working properly

    hi,
    Something is wrong with my Engineer’s Thumb, I need your help!

    I can hear my guitar only when the Ratio pot is set to minimum, weirdly when I tap on the pot I can hear the tap amplified out of my amp...so I measured some readings with my multimeter, but I can’t figure out where the issue is.

    I attach a pic that shows the voltage readings in the schematic.
